Pest control officials in Minnesota are monitoring a high number reports of aggressive biting gnats. Alex Carlson with the Metropolitan Mosquito Control District says they are investigating to see if this is due to a new type of gnat, or traditional black flies we always see in Minnesota.

“Most of these black flies are single generation and they only last about two to three weeks. For people that are getting it really bad, even if we’re not able to get to them this year they’re not going to last all summer long.”

The largest number of reports so far are centered in the South Twin Cities Metro. Carlson says these types of pests do not spread diseases and the best prevention are traditional bug sprays, wearing light clothing, protecting your neck area and avoid overly fragrant shampoo or lotions.
